have a REJECT button in gating

[vbenes]

Hi,
if we see a gating fail (or any other serious fail here and there) we should be able to mark the build as broken (rejected). Otherwise, devel might be unsure if the build was already inspected and just not waived.

In addition, we would see a ratio of failing gating tests that were rejected or waived, which is in my opinion useful as well.

Yeah this is definitely something we could use 👍
